Be it known'that I, EnwARoCox, a nativebornscitizen 'of theUnited States, residing vatOroville', in the county of Okano-gan and State,..of 'VVashington, have invented new and useful Improvements in Current-Motors, of which the following is a specificatio-n.-

Specification of Letters Patent.

This invention relates to current motors .for operating. pumps or other machinery,

the primary object of the invention being to provide a simple and eflicient type of rotary n1oto1-' which may be mounted upon an inclined bank or other sloping support so that a certain proportion of the paddles will be submerged for the action of the current thereon, while. the remainder of the paddles will stand out of the water and move without resistance to the rotation of the motor, said motor being adjustable to vary the] working path of the paddles, according to the ground in the level of the water.

A further object of the invention is to provide a motor of this character foropcrating a novel construction of pumping mechanism, whereby a large volume of water may be pumped with considerable delivery force within a minimum amount of time.

The invention consists of the features of construction, combination and arrangement of devices, hereinafter fully described and claimed, reference being had to the accompanying drawings, in, which v Figure 1 is a top plan view of a current motor and ump embodying my invention. Fig. 2 is a slde elevation of the same. is a vertical section on the line -3-3 of Fig. 1. Fig. 4 is. a sectional plan view on the line 44 of Fig. 1. I

Referring to the drawings, 1 designates a stationary sloping support mounted upon the inclined bank of a stream and provided with track rails 2 for the wheels 3 of a movable carrier frame or truck 4 to run upon, a greater or less portion of said support being submerged in the water of the stream. Thetruck is movable upon the inclined way formed by the supporttoward and from the ing lines 5, which may be fastened'to stakes or other anchoring members embedded in proper proximity to the bank of the stream.

The truck 4 carries a pedestal 6 provided with a bearing 7, and below said pedestal CURRENT-MOTOR.

carries a bearing 8, in whichibearings is journaled a shaft 9, to which is keyed, at a suitable point above the bearing 7, the hub 10 of a rotary motor wheel, comprising said hub and an annular series of radial arms. 11 fixed at their'inner ends to the hub and carrying at their outer ends vertically disposed paddles or blades12, which may be of any suitable form and construction. The wheel rotates -in the direction of the arrow shown in Fig. l by the action of the current upon the blades 12, two or more of which are submerged at a time for the transmission of power to the wheel. The arms 11 are stayed and reinforced from the upper projecting end of the shaft by suitable braces 13 and are su ported from the pedestal 6 by wheels or vrol em 14 arranged to travel upon an annuproper working depth, whereby the wheel may be adjusted on its inclined way to arrange the blades for action according to the level of the water. Itwill thus be seen that through the inclined arrangement of the wheel a certain number or proportion of the blades will be submerged at a time for working action, while the remainder of the blades will be entirely out of the water and moving through the air, thus obviating the necessity of feathering; the non-working blades to decrease their resistance, while at the same time enabling the blades to be submerged in operation to any degree desired.

In connection with the motor, I provide an improved pumping apparatus comprising cylinders 15 and 16 arranged longitudinal-ly at opposite sides of the truck, said cylinders being provided at their lower ends with suction pipes 17 and discharge pipes 18, the suction pipes-being arranged to draw water from the stream and the discharge pipes being connected by a branch pipe 19 with'a delivery pipe 20 leading {in practice {p any suitable point where the .water is to s stored or used. The pistons 21 of the respective cylinders are connected by links 22 with the opposite ends of a cross bar or head 23 pivoted for lateral oscillating movement at 24 upon the upper end of the truck. Connected with the bar 23 at a point in line with its fulcrum and extending downwardly therefrom is an arm 25.

which extends beneath the edestal 6 and is bar 23 will be moved in one direction to 0p erate one of the pistons on its suction'stroke and the other piston on its discharge stroke, while in the other half revolution of the crank'the pistons will be respectively operated in the reverse directions. A continuous pumping action will thus be. set up to supply a large quantity of water under a comparatively high pressure within a minimum period of time.

Having thus described invention, .1

claim 2- A current motor comprising a sloping support, truck .ra-ils on said support, a carriage provided with wheels to travel onsaid track rails, means for raising and lowering the carriage, pump cylinders arranged longi 'tudinally at opposite sides of the carriage adjacent the lower end thereof and provided at their lower ends with suction'and discharge pipes, a delivery pipe connected with. said discharge pipes, a transversely arranged oscillating bar at the upper end of the carriage,'1inks connecting the ends of said bar with the-pump pistons, a slotted actuating bar connected with said oscillating bar, an annular track upon the carnage,

a vertical shaft journaled on the carriage concentric with the trackand extending above and below the same and provided at its lower end with a crank operating in theslot of the actuating bar, an inclined wheel mounted on the upper end of said shaft and provided with wheels or rollers to run upon said annular track, and an annular series of fixed bladessupported by the wheel and inclined to the plane of travelthereof. t In testimony whereof I aflix my signature in presence of two witnesses.
